Mitogen-activated protein kinase-dependent activation of the na+/H+ exchanger is mediated through phosphorylation of amino acids ser(770) and ser(771)
Download2007-01-01
Malo, Mackenzie E., Li, Liang, Fliegel, Larry
We investigated regulation of the type 1 isoform of the Na+/H+ exchanger by phosphorylation. Four specific groups of serine and threonine residues in the regulatory carboxyl-terminal tail were mutated to alanine residues: group 1, S693A; group 2, T718A and S723A/S726A/S729A; group 3,...

Molecular cloning of cDNA encoding a 55-kDa multifunctional thyroid hormone binding protein of skeletal muscle sarcoplasmic reticulum
Download1990-01-01
Fliegel, Larry, Newton, E., Burns, K., Michalak, M.
A cDNA clone encoding 55-kDa multifunctional, thyroid hormone binding protein of rabbit skeletal muscle sarcoplasmic reticulum was isolated and sequenced. The cDNA encoded a protein of 509 amino acids, and a comparison of the deduced amino acid sequence with the NH2-terminal amino acid sequence...

Molecular cloning of the high affinity calcium binding protein (calreticulin) of skeletal muscle sarcoplasmic reticulum
Download1989-01-01
Fliegel, Larry, Burns, K., Reithmeier, F. A. F., MacLennan, D. H., Michalak, M.
A cDNA clone encoding the high affinity Ca2+-binding protein (HACBP) of rabbit skeletal muscle sarcoplasmic reticulum was isolated and sequenced. The cDNA encoded a protein of 418 amino acids, but a comparison of the deduced amino acid sequence with the NH2-terminal amino acid sequence of the...

Na+/H+ exchange in the tumour microenvironment: Does NHE1 drive breast cancer carcinogenesis?
Download2015-01-01
Amith, Schammim Ray, Fong, Sunny, Baksh, Shairaz, Fliegel, Larry
Ionic messengers signal several critical events in carcinogenesis, including metastasis, the leading cause of patient mortality. The aberrant metabolic, proliferative and anti-apoptotic nature of neoplastic cells can be traced to the abnormal expression of their ion transporters and related...

Na+/H+ exchanger isoform 1-induced osteopontin expression facilitates cardiomyocyte hypertrophy
Download2015-01-01
Mohamed, Iman A., Gadeau, Alain-Pierre, Fliegel, Larry, Lopaschuk, Gary, Mlih, Mohamed, Abdulrahman, Nabeel, Filmore, Natasha, Mraiche, Fatima
Enhanced expression and activity of the Na+/H+ exchanger isoform 1 (NHE1) has been implicated in cardiomyocyte hypertrophy in various experimental models. The upregulation of NHE1 was correlated with an increase in osteopontin (OPN) expression in models of cardiac hypertrophy (CH), and the...

Na+/H+ exchanger NHE1 regulation modulates metastatic potential and epithelial-mesenchymal transition of triple-negative breast cancer cells
Download2016-01-01
Amith, Schammim Ray, Wilkinson, Jodi Marie, Fliegel, Larry
In triple-negative breast cancer (TNBC), the high recurrence rate, increased invasion and aggressive metastatic formation dictate patient survival. We previously demonstrated a critical role for the Na+/H+ exchanger isoform 1 (NHE1) in controlling metastasis of triple-negative cells. Here, we...

Protein Kinase Mediated Regulation of the Na+/H+ Exchanger in the Rat Myocardium by MAP-Kinase-dependent Pathways
Download1999-01-01
Moor, Andrea Noor, Fliegel, Larry
We examined regulation of the Na+/H+ exchanger isoform 1 by phosphorylation in the rat myocardium. We utilized cell extracts from adult rat hearts, adult rat extracts fractionated by fast performance liquid chromatography, and extracts from cultured neonatal cardiac myocytes. The...

Regulation of Na+/H+ Exchanger Gene Expression: Role of a poly T rich region in regulation of expression of the NHE1 promoter
Download1996-01-01
Yang, Weidong, Wang, Huayan, Fliegel, Larry
In this study we examine regulation of expression of the Na+/H+ exchanger promoter in L6 and NIH 3T3 cells. We have identified a highly conserved poly(dA·dT)-rich region that appears to be important in regulation of expression of the NHE1 gene. Deletion or mutation of this region results in...

Specific Activation of the Na+/H+ exchanger gene during neuronal differentiation of embryonal carcinoma cells
Download1995-01-01
Dyck, Jason R. B., Fliegel, Larry
We examined the regulation of the NaGraphic/HGraphic exchanger gene during differentiation of the P19 mouse embryonal carcinoma cells. Treatment of P19 cells with retinoic acid induces the development of neurons, astroglia, and microglia cells. Upon retinoic acid-induced differentiation of P19...

Stop codon polymorphisms in the human SLC9A1 gene disrupt or compromise na+/H+ exchanger function
Download2016-01-01
Li, Xiuju J., Augustine, Aruna, Chen, Shuo, Fliegel, Larry
The NHE1 isoform of the mammalian Na+/H+ exchanger is a ubiquitous plasma membrane protein that regulates intracellular pH in mammalian cells by removing one intracellular proton in exchange for one extracellular sodium. Deletion of the NHE1 gene (SLC9A1) affects the growth and motor ability of...
